1 4
2 6
3 8

When there are more than two alleles controlling the same character. They are called
1 Pleiotropy
2 Polyalleles
3 Multiple alleles
4 All of these
Explanation:
When there are more than two, i.e., three alleles, governing the same character. Since in an individual only two alleles can be present, multiple alleles can be found only when population studies are made.

Which of the following is a mismatch?
1 Phenotypic \(\mathrm{F}_{2}\) ratio of 3:1 - Monohybrid cross
2 Phenotypic \(\mathrm{F}_{2}\) ratio of 3:1 - partial dominance
3 Phenotypic \(\mathrm{F}_{2}\) ratio of 1:2:1 - Incomplete dominance
4 Phenotypic \(\mathrm{F}_{2}\) ratio of 1:2:1 - codominance
Explanation:
Phenotypic F2 ratio of 15:1 is seen in Phenotypic F2 ratio of 9:3:4 is seen in recessive epistasis. Phenotypic F2 ratio of 1:2:1 is seen in co-dominance. And Phenotypic F2 ratio of \(3: 1\) is seen in monohybrid inheritance and not in partial dominance.

The probability of having a child with blood group O to parents with blood groups A and B is
1 1 out of 4
2 2 out of 4
3 4 out of 4
4 3 out of 4
Explanation:
After all the blood group of parents are A and B, accordingly the their genotypes would be AO and BO. Thus, the desirable genotypes of their children will be AO, BO, AB and OO i.e., the probable blood groups are A, B,AB and O (that means any one out of these four) .
